Description

Technical Field

[0001] The utility model relates to an atomizing device. Background Art

[0002] Liquid atomizers are widely used in modern technology and life, including medical, agricultural, humidification, air purification and many other fields. Specifically for personal care equipment, such as combs, head care and facial care equipment, atomizers play an important role. These devices convert liquids (such as essential oils, care solutions, etc.) into fine droplets, which act directly on hair or skin to improve the care effect.

[0003] Traditional liquid atomization devices generally include a liquid storage bin, a liquid storage tank, an atomizer sheet, and a liquid transmission pipeline system. As a core component, the atomizer sheet atomizes the liquid into fine particles through ultrasonic vibration or other means. However, there is a key problem with existing atomization devices: the liquid that has been in the liquid storage bin for a long time will leak through the atomizer sheet. This phenomenon not only leads to liquid waste, but also affects the performance and user experience of the device. In personal care devices, this leakage problem is particularly prominent because it may cause liquid to overflow, contaminate the user's hair or skin, or even damage the device.

[0004] Although attempts have been made in the prior art to reduce liquid leakage by optimizing design and material selection, the results are not satisfactory. In particular, in small portable devices such as combs, head care and facial care, the leakage problem is more serious due to space limitations and high liquid mobility. Utility Model Content

[0005] The utility model aims to provide an atomizing device which can avoid leakage of liquid through an atomizing sheet.

[0006] The purpose of the utility model is achieved in this way:

[0007] An atomizing device, comprising a liquid storage bin, a liquid storage tank, a water pump and an atomizing sheet, wherein the liquid storage bin is provided with an atomizing sheet mounting port, a liquid inlet port and a liquid discharge port, wherein the atomizing sheet mounting port, the liquid inlet port and the liquid discharge port are connected to an inner cavity of the liquid storage bin, and the atomizing sheet is arranged at the atomizing sheet mounting port;

[0008] The liquid storage tank is provided with a liquid discharge outlet and a liquid circulation inlet, and the liquid discharge outlet and the liquid circulation inlet are connected to the liquid storage tank;

[0009] The liquid discharge outlet is connected to the water inlet of the water pump, the water outlet of the water pump is connected to the liquid inlet of the liquid storage bin, and the liquid discharge outlet of the liquid storage bin is connected to the liquid circulation inlet of the liquid storage tank;

[0010] The liquid discharge port of the liquid storage bin is provided with a one-way valve for preventing the liquid in the liquid storage bin from flowing back to the liquid storage bin.

[0011] Prevent liquid leakage: By setting a one-way valve at the discharge port of the liquid storage bin, the liquid in the liquid storage bin is effectively prevented from flowing back to the atomizer, which fundamentally solves the leakage problem caused by long-term retention of liquid. This design ensures that the liquid can only flow in one direction, avoids the phenomenon of liquid seeping from the atomizer, and improves the working efficiency and service life of the device.

[0012] Improve liquid utilization: Since the liquid will not leak through the atomizer, the liquid can be fully utilized to maximize the atomization effect. This not only saves liquid resources, but also reduces unnecessary waste, especially when using high-value care liquid or liquid medicine, the economic benefits are more significant.

[0013] Improve user experience: When applied to combs, head care and facial care equipment, the anti-leakage design avoids the inconvenience and pollution caused by liquid spillage, ensuring the comfort and cleanliness of users during use.

[0014] Simplified maintenance: By setting a one-way valve, the flow path of the liquid in the atomization device is more clear and controllable, reducing the chance of liquid retention and deposition. At the same time, preventing liquid leakage also reduces the risk of equipment failure caused by liquid erosion or contamination, and improves the reliability and stability of the device.

[0015] Multi-angle use: Under the action of the water pump, the liquid does not need to rely on gravity to flow to the liquid storage tank, allowing users to use the atomizer at any angle. This feature greatly improves the flexibility and convenience of the device, adapts to a variety of usage scenarios and needs, and is particularly suitable for portable and handheld devices.

[0016] The purpose of the utility model can also be solved by the following technical measures:

[0017] Furthermore, it also includes a liquid guiding device, which includes a liquid guiding hose and a gravity ball. The liquid guiding hose is placed in the liquid storage box, one end of the liquid guiding hose is connected to the liquid discharge outlet, and the gravity ball is arranged near the other end of the liquid guiding hose.

[0018] Guaranteed liquid extraction efficiency: The gravity ball in the liquid guide device ensures that the liquid guide hose is always at the bottom of the liquid in the liquid storage tank. Even if the amount of liquid in the liquid storage tank is small or the equipment is tilted, the water pump can continue to extract liquid efficiently. This design ensures the normal operation of the atomization device under various conditions of use, improving the reliability of the equipment and user satisfaction.

[0019] Furthermore, the liquid storage tank is provided with a liquid injection port, and the liquid injection port is connected to the inner cavity of the liquid storage tank.

[0020] Convenient liquid addition: The liquid storage tank is provided with a liquid filling port, which is connected to the inner cavity of the liquid storage tank, so that users can easily add liquid. Liquid can be added without disassembling the device or opening the liquid storage tank, which improves the convenience and user-friendliness of the device.

[0021] Furthermore, the liquid storage tank is provided with a one-way valve or a micropore communicating with the atmosphere.

[0022] Preventing negative pressure from forming: The liquid storage tank is equipped with a one-way valve or micro-hole connected to the atmosphere to ensure that negative pressure will not form in the liquid storage tank when the water pump is pumping liquid, thus ensuring the smoothness and continuity of the pumping process. This design effectively prevents the difficulty or interruption of pumping liquid due to negative pressure, and further improves the stability and reliability of the equipment.

[0023] Furthermore, it also includes a pipe plug assembly that facilitates detachable connection between pipes. The pipe plug assembly is arranged between the discharge inlet of the liquid storage tank and the water inlet of the water pump, and the pipe plug assembly is arranged between the liquid circulation inlet of the liquid storage tank and the discharge port of the liquid storage tank.

[0024] By arranging a pipe plug assembly between the liquid discharge inlet of the liquid storage tank and the water inlet of the water pump, and between the liquid circulation inlet of the liquid storage tank and the liquid discharge port of the liquid storage bin, the pipe connection is made more convenient. When the liquid storage tank is a detachable liquid storage tank, the pipe plug assembly can be used to quickly connect the pipes of the liquid storage tank, which is convenient for users to disassemble and clean the liquid storage tank, thereby improving the maintenance efficiency and convenience of the equipment.

[0025] Furthermore, the liquid storage bin is built with filter cotton or liquid absorbent cotton.

[0026] Improve atomization effect: Built-in filter cotton or liquid absorbent cotton in the liquid storage bin can effectively prevent solid particles from clogging the atomization hole and protect the normal operation of the atomizer. At the same time, the filter cotton or liquid absorbent cotton can increase the contact area between the liquid and the atomizer, making the atomization more uniform and improving the atomization effect. This design ensures the stability and efficiency of the atomization process and improves the user experience.

[0027] Furthermore, it also includes a control circuit, the water pump and the atomizer are electrically connected to the control circuit respectively, and the control circuit has a built-in control method for preventing liquid from remaining in the liquid storage bin.

[0028] Preventing liquid residue: By building a control method to prevent residual liquid in the liquid storage bin into the control circuit, the closing time of the atomizer is delayed after the water pump is turned off, so that the atomizer has enough time to deal with the remaining liquid in the liquid storage bin, thereby ensuring that the liquid in the liquid storage bin is completely atomized and avoiding long-term accumulation of liquid. This design effectively prevents liquid from leaking along the atomizer, improving the cleanliness and maintenance convenience of the equipment.

[0029] Intelligent control: The control circuit is electrically connected to the water pump and the atomizer, which facilitates intelligent control. The working state of the water pump and the atomizer is controlled by setting a program to ensure the stability and efficiency of the equipment operation. Intelligent control not only improves the user experience, but also increases the safety and reliability of the equipment.

[0030] The beneficial effects of the utility model are as follows:

[0031] The utility model sets a one-way valve at the discharge port of the liquid storage bin to effectively prevent the liquid from flowing back to the atomizing plate, solving the leakage problem caused by long-term retention of liquid. This design ensures that the liquid can only flow in one direction, avoids the phenomenon of liquid seeping through the atomizing plate, and improves the working efficiency and service life of the device.

[0032] The utility model, under the action of the water pump, does not need to rely on gravity to achieve the flow of liquid to the liquid storage bin, so that the user can use the atomization device at any angle. The gravity ball design in the liquid guide device ensures that the liquid guide hose is always located at the bottom of the liquid, and the water pump can effectively pump liquid no matter how the device is tilted or moved. This greatly improves the flexibility and convenience of the device, adapts to a variety of usage scenarios and needs, and is particularly suitable for portable and handheld devices.

[0033] The utility model provides a liquid filling port in the liquid storage tank, which is connected to the inner cavity of the liquid storage tank, so that the user can add liquid conveniently. Liquid can be added without disassembling the device or opening the liquid storage tank, which improves the convenience and user-friendliness of the device.

[0035] The utility model makes the pipe connection more convenient by arranging a pipe plug assembly between the liquid discharge inlet of the liquid storage tank and the water inlet of the water pump, and between the liquid circulation inlet of the liquid storage tank and the liquid discharge port of the liquid storage bin. When the liquid storage tank is a detachable liquid storage tank, the pipe plug assembly can be used to quickly connect the pipes of the liquid storage tank, which is convenient for users to disassemble and clean the liquid storage tank, thereby improving the maintenance efficiency and convenience of the equipment.

[0036] The utility model has built-in filter cotton or liquid-absorbing cotton in the liquid storage bin, which can effectively prevent solid particles from clogging the atomization hole and protect the normal operation of the atomization plate. At the same time, the filter cotton or liquid-absorbing cotton can increase the contact area between the liquid and the atomization plate, making the atomization more uniform and improving the misting effect. This design ensures the stability and efficiency of the atomization process and improves the user experience.

[0037] The utility model has a control method built into the control circuit to prevent residual liquid in the liquid storage bin. After the water pump is turned off, the closing time of the atomizer is delayed, so that the atomizer has enough time to process the residual liquid in the liquid storage bin, thereby ensuring that the liquid in the liquid storage bin is completely atomized and avoiding long-term accumulation of liquid.
